I love maps, I could stand hours in front one, whether it represents my city or the entire world; whether it hangs on a wall or it twist at my fingertips on my tablet. It is quite a creative and cheap way to travel! I just finished a fascinating book: A History of the World in 12 Maps, written by a British professor, Jerry Brotton. He explains how humans have always been driven to represent the world around them, and how each of these representations is shaped by cultural, political or commercial interests. Google Earth is no exception.
